(04-21) 17:38 PDT MILL VALLEY -- The death of a Mill Valley woman on Mount Tamalpais last week does not appear to be the result of foul play, investigators said Monday.

The body of Marie Sanner, 50, was found Thursday near the Matt Davis Trail at Fern Creek, where she had been hiking alone.

A forensic examination completed Monday revealed no signs of an assault, according to the Marin County Sheriff's Office, though the agency said the cause of death is yet to be determined. Investigators continue to look into what happened to Sanner and are awaiting toxicology reports.

Sanner's death follows the death of another solo female hiker this month, an occurrence that has sparked concern among many who visit the popular Mount Tamalpais State Park.

The body of Magdalena Glinkowski, 33, was found in the same area April 12, also in a trailside drainage. Her body showed no signs of trauma, the sheriff's office said, but an official cause of death is pending.
